I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
It depends on the crime, but in general I guess you look for how the perpetrator got in, how they got out, and what they disturbed while they were there. Then I look for what we could get information from (such as surfaces that they had to touch that are smooth and glossy and might have prints, whether they left blood or bodily fluids behind that could be tested, whether they wrote something or used something that could point to their identity, etc.).

No. A .357 can shoot .38 bullets (not vice versa, or the gun will blow up) but 9mm can't shoot 38 bullets because they're shaped a little differently. It's confusing because what we call .38 caliber are actually .357, and 9mm is actually .380--in size, but a 9mm gun cannot shoot .380 bullets. You would have to read the forensic report carefully and maybe ask for clarification. I've never worked in ballistics, so perhaps there's a chance that the report is saying that the projectile had a .380 diameter, not that it was a .380 bullet, in which case it could have come from a 9mm gun?

After I spent 10 years as a secretary, bored out of my mind. I always liked mysteries and I liked science, but I never really thought about putting them together until long after my first round at college.

I'm very interested now in phone number 'spoofing' that the telephone scammers use to call us, but the technology is a little beyond my ken. Actually a lot beyond my ken. I have a co-worker who could explain it but we never have time.

Is it ok w/your employer if you babysit one of the kids outside of daycare hours?
I don't solve cases. Detectives solve cases. I suppose I actually 'solve' them when I get a fingerprint hit for a burglary where there would have been no other way to ever identify the burglar. That happens maybe 5-10 times a year. Otherwise forensic science is usually confirming or eliminating factors that are already suspected, and often provides information (say, what caliber of gun was used or where the burglar got into the house) that doesn't point to the identity of the criminal but adds details to the overall event.

Unless he actually ejaculated in his underwear, I don't see why there would be sperm in underwear he simply wore. But maybe that's one of those questions about men I'd just rather not know! I'm also not sure that semen would go back into solution when re-wetted like sugar or salt. So it might be possible, for all I know, but you'd probably have to ask a serologist or DNA technician. I'm sorry I can't be more help.

If there was semen on the toilet seat and it was still wet and sticky enough to stick to skin and then be transferred to underwear, then I suppose it would be possible.
